Required parameters : None

Optional parameters : None

Encoding considerations : Binary

Security considerations : 
These files are intended to be read by a proprietary client (the "Unsealer") which 
makes the unencrypted content available in a very limited fashion to a user's 
system. As the data format is private and encrypted using well-known algorithms, 
it is unlikely that the data could be spoofed. The client is also designed 
to refuse to work with data that is corrupt or ill-formed. This data does not contain 
any executable material. Although this file type will be displayed as a 
Microsoft Office file type, all macro and scripting functionality is disabled 
by the Unsealer client.

Interoperability considerations : 
This mime-type is valid for Windows systems only.

Published specification : 
The specifications for this content-type are proprietary. They are specified 
by Sealed Media. The registration of this content-type is intended only to 
provide a convention for labeling this proprietary data type within the 
MIME/HTTP environment and does not specify any details about the content 
format or semantics, except to refer to the software and specifications 
provided by Sealed Media. Company information may be obtained at

Applications which use this media : 
This mime-type is intended for use only by the client software, 
"Unsealer", created by Sealed Media.
